What is berkelium used for in everyday life?
Berkelium-249 (330-day half-life) has been widely used in the chemical studies of the element because it can be produced in weighable amounts that are isotopically pure by nuclear reactions beginning with curium-244. The only use of berkelium has been in the synthesis of heavier elements such as tennessine.
How is berkelium formed?
Berkelium is artificially produced, and has only been produced in relatively small amounts. It can be made through bombarding 241Am, an isotope of americium, with alpha particles using a cyclotron. This yields 243Bk and two free neurons. Numerous alloys and compounds of berkelium have been prepared and studied.

Is berkelium a metal?
Berkelium is a radioactive, silvery metal.
What is the flammability of terbium?
Specific Hazards Arising from the Material: Flammable in the form of dust when exposed to heat, sparks or flame. May react with water under fire conditions to liberate flammable hydrogen gas. May emit fumes of terbium oxide under fire conditions.
What is terbium boiling point?

What are 3 uses for berkelium?
Uses of Berkelium
- Presently, the element is not used biologically or for technological purposes.
- It was used for the atmospheric nuclear weapons tests between 1945 and 1980.
- Its isotopes are used for basic scientific research.
Is berkelium radioactive?
Berkelium is one of 15 actinides, elements with atomic numbers 89 to 103. Because these rare, heavy metal isotopes are radioactive, they are difficult to study.
